Claims

[Scope of utility model registration request]

An arm is attached so as to be slidable along the main body which is pivotally supported on the base, and a claw for attaching a wheel is provided at the tip of the arm, while the base is attached so as to be slidable along the main body. In the tire attachment/detachment device, a bead roller is mounted on the base and a bead roller is mounted on the base, an upright body is pivotally supported on the legs provided on the base, and a holder to which the bead roller is attached is mounted on the upright body. The upright cylinder is attached in a slidable manner, one end of the upright cylinder is fixed at a certain distance from the shaft on which the upright body is pivotally supported, and a piston rod protruding from the upright cylinder is rotatably supported on the upright body. A stopper is provided to connect with the locking piece that has been inserted and further restrict the rotation of the locking piece. A bead roller erecting mechanism in a tire mounting/detaching device, characterized in that the erecting cylinder is formed on a base side, and the central axis of the erecting cylinder is separated by a certain distance from the fixing axis of the erecting body.
